Two cyclists, 96 miles apart, start riding toward each other at the same time. One cycles 3 times as fast as the other. If they
JulsSmile [24]
<span>18 mph. OK. Let's call the speed of the slower cyclist X, And since the faster cyclist is 3 times faster, that speed will be 3X. So their combine closing speed will be (X + 3X) and over a period of 4 hours, they travel 96 miles. So the equation becomes: 4(X + 3X) = 96 Now solve for X 4(X + 3X) = 96 4(4X) = 96 16X = 96 X = 6 So the slower cyclist has a speed of 6 mph. And since the faster cyclist is 3 times faster, that speed is 3*6 = 18 mph.</span>

To solve the system of equations below, Maria isolated the variable y in the first equation and then substituted it into the sec
3241004551 [841]

Answer:

  x^2 +4x = 18

Step-by-step explanation:

The variable y is isolated in the first equation by dividing both sides by the coefficient of y:

  3y = 12x . . . . . . given

  3y/3 = 12x/3 . . . . . divide by the coefficient of y

  y = 4x . . . . . . . simplify

__

This expression (4x) is put in place of y when substitution is used.

  x^2 +y = 18 . . . . given

  x^2 +4x = 18 . . . . . with 4x substituted for y
